According to Technomic's Generational Consumer Trend Report, the Millennial generation, aged 18 to 33, rivals the Baby Boomer generation in size. As a result, restaurant chains are adjusting their tactics to make their foodservice operations more appealing to this sizable demographic.

Some examples of restaurant amenities Millennials go for and accommodating chains include:

Late night service:

Taco Bell offers a "4th meal"

Denny's runs an all-nighter promotion at select locations

Super indulgent offerings:

KFC's double down sandwich

Friendly's grilled cheese sandwich patty melt

Carl's Jr. footlong cheeseburger

Community outreach, fresh food and lounge layout:

Burgerville combines all three

Other key Technomic findings:

Three out of four Millennials visited Facebook within 30 days, significantly more than Gen Xers (66percent) and Boomers (50 percent)

Half of Millennial consumers say they enjoy trying new restaurants and think it is important to try different types of foods

Millennials are very interested in French, Thai and Spanish cuisine

75: The percent of Millenials who feel restaurants are a great place to gather with friends. In contrast, only 68 percent of Baby Boomers share this perspective.
